A strong REF CURSOR type specifies a return type, which is the RECORD type of its cursor variables. The PL/SQL compiler does not allow you to use these strongly typed cursor variables for queries that return rows that are not of the return type. Strong REF CURSOR types are less error-pro...
it is very much like aprocedure; it can be forward declared and the declaration and the definitioncan be split between a package and its body; and it can have
Every time you run either a SQLDML statement or a PL/SQLSELECTINTOstatement, PL/SQL opens animplicit cursor. You can get information about this cursor from its attributes, but you cannot control it. After the statement runs, the database closes the cursor; however, its attribute values remai...
(1)If CURSOR_SPACE_FOR_TIMEis set to false (the default), then a cursor can be deallocated from the library cache regardless ofwhether application cursors associated with its SQL statement are open.In this case, Oracle Database must verify that the cursor containing the SQLstatement is in th...

Summary: In this tutorial, you will learn about the PL/SQL cursor and its usage. A cursor is a pointer that points to the result of a query. PL/SQL has two types of cursors: Implicit cursors Explicit cursors Implicit cursors# Whenever Oracle executes an SQL statement such asSELECT INTO,...
(2)If CURSOR_SPACE_FOR_TIMEis set to true, then a cursorcan be deallocated only when all application cursors associated with itsstatement are closed. In this case, Oracle Database need not verify thata cursor is in the cache because it cannot be deallocated while an applicationcursor associat...
